<span>The correct answer is A. water. That's because water's chemical composition is such that it can't be decomposed and turned into a fuel. Unlike Corn, sugar cane, and wood, it can't be used to power machines. The other ones are organic and can be used as biofuel, while wood can even be used in the form of coal as coal is nothing else than wood.I hope that my answer is helpful!

Answer:
30 minutes
Explanation:
Bacteria reproduce by binary fission, a process by which one parent cell divides to form 2 progeny cells. Because one cell produces 2 progeny cells, bacteria are said to undergo exponential ( logarithmic) growth.
As in the case of staphylococcus aureus, we start with 100 cells , and after 90 minutes number becomes 800 that means , firstly the cells doubled (100 x 2 = 200 ) after 30 minutes. Again after 30 minutes they doubled ( 200 x 2 =400 ) and again after 30 minutes they doubled (400 x 2 = 800). So in 90 minutes 100 cells became 800 cells.
Hence the generation time for S.aureus is 30 minutes.
Answer: An essay is a common type of academic writing that you'll likely be asked to do in multiple classes. Before you start writing your essay, make sure you understand the details of the assignment so that you know how to approach the essay and what your focus should be. Once you've chosen a topic, do some research and narrow down the main argument(s) you'd like to make. From there, you'll need to write an outline and flesh out your essay, which should consist of an introduction, body, and conclusion. After your essay is drafted, spend some time revising it to ensure your writing is as strong as possible.
